Subject: [PATCH RFC 0/5] drm/msm: dpu1: correctly implement SSPP & WB Clock
 Control Split

Starting with the SM8550 platform, the SSPP & WB Clock Controls are
no more in the MDP TOP registers, but in the SSPP & WB register space.

Add the corresponding SSPP & WB ops and use them from the vbif QoS
and OT limit setup functions.

Neil Armstrong (5):
      drm/msm: dpu1: create a dpu_hw_clk_force_ctrl() helper
      drm/msm: dpu1: add setup_clk_force_ctrl() op to sspp & wb
      drm/msm: dpu1: vbif: add dpu_vbif_setup_clk_force_ctrl() helper
      drm/msm: dpu1: call wb & sspp clk_force_ctrl op if split clock control
      drm/msm: dpu1: sm8550: move split clock controls to sspp entries
